What is the disadvantage of I2C?

Drawbacks or disadvantages of I2C ➨The hardware complexity increases when number of master/slave devices are more in the circuit. ➨It is half duplex mode of communication. ➨The protocol is managed by software stack. This increases processing overheads on the µP and µC.

Why is I2C so popular?

I2C is incredibly popular because it uses only 2 wires, and like we said, multiple devices can share those wires, making it a great way to connect tons of sensors, drivers, expanders, without using all the microcontroller pins.

Where is I2C being used?

I2C is a serial protocol for two-wire interface to connect low-speed devices like microcontrollers, EEPROMs, A/D and D/A converters, I/O interfaces and other similar peripherals in embedded systems. It was invented by Philips and now it is used by almost all major IC manufacturers.

What is disadvantage of SPI interface?

Disadvantages of SPI: It requires more signal lines (wires) than other communications methods. The communications must be well-defined in advance (you can’t send random amounts of data whenever you want) The controller must control all communications (peripherals can’t talk directly to each other)

Which of the following is the disadvantages in SPI?

Following are the disadvantages of SPI: ➨It uses one CS line per slave and hence hardware complexity increases if slave devices are more in the design. ➨In order to add slave device, software needs to be changed and extra CS line is required to be added. ➨No flow control and no acknowledgment used in SPI.

What are the advantages of I2C communication?

I2C communication or protocol has a significant edge over its peers such as serial port communication and SPI. Let us have a look into the various advantages that renders the I2C protocol so effective for short distance intra-board communication. 1.

What are the advantages of SPI over I2C?

While I2C’s wiring simplicity and standardization are significant advantages, SPI has some attractive features as well. 1. Communication. Separate MISO/MOSI data lines mean that it’s capable of full-duplex communication, as opposed to I2C’s half-duplex operation, meaning that data send and receive transmissions must alternate.

What are the advantages of I2C over UART?

The advantages of I 2 C can be summarized as follows: We can see from these points that I 2 C is especially suitable when you have a complicated, diverse, or extensive network of communicating devices. UART interfaces are generally used for point-to-point connections because there is no standard way of addressing different devices or sharing pins.

What is an I2C circuit?

• I2C stands for Inter-Integrated Circuit. • It uses only two lines between multiple masters and multiple slaves viz. SDA (Serial Data) and SCL (Serial Clock). • It is synchronous communication like SPI and unlike UART. Hence there is common clock signal between masters and slaves.
